Private Clouds Offers Cost Savings

Introduction

Cloud computing delivers IT capabilities as services-on-demand. This scalable and elastic model provides advantages like faster time-to-market, no capex and pay-per-use business model. While there are some such benefits, there are trials in taking up public clouds because of dependency on infrastructure that is not completely controlled internally and rather shared with outsiders(Nurmi & Wolski 2008). Several enterprises, particularly large ones that have currently invested in their own infrastructure over the years are looking at setting up personal clouds within their organizational boundaries to reap the benefits of cloud computing technologies leveraging such investments. (www.cisco.com) This paper describes the distinct options available, highlighting the key advantages and trials impersonated by each and the approach enterprises should be taking in taking up cloud computing with minimal risk.

Public Clouds and Challenges

Public clouds like Amazon AWS, Microsoft Azure, Google AppEngine offer infrastructure and stages as services over the internet. In public clouds, resources and charges are distributed by users who use them over the internet on pay per use model. (Foley 2008)This model requests especially to startups and little associations that have not invested in hardware assets and are looking for ways to bypass the large capex involved in procuring infrastructure upfront. Even though there are some advantages like cost savings, faster time to market, etc., from this form, there are a couple of challenges listed underneath that are stopping broad scale adoption of public clouds.

Security: The large-scale roadblock is the potential security issues due to multitenant environment of public clouds. There are security and privacy anxieties with distributing same physical hardware with unknown parties that need to addressed. (Foley 2008)

Reliability and presentation: presentation and accessibility of the submissions are significant criteria defining the achievement of an enterprise's business. However, the fact that organizations lose control over IT environment and important success metrics like performance and reliability, (Staten, 2009 )and are dependent on factors outside the control of the IT organizations makes it dangerous for some mission critical applications.

Vendor Lock-in: Cloud computing services suggested by distinct vendors are not ruled by any standards as of today. (Foley 2008) Depending on the vendor, the submissions have to undergo changes to acclimatize to the service.

Leveraging living Investment: Most large associations that have currently invested in their own facts and figures hubs would glimpse a need to leverage those investments as an important benchmark in taking up cloud computing. (Staten, 2009 )

Corporate Governance and Auditing: accomplishing governance and auditing undertakings with the business data abstracted in the public cloud impersonates challenges, that are yet to be addressed. (Foley 2008)

Maturity of the Solutions: Some of the PaaS offering like AppEngine offer limited capabilities like only a subset of JDO API. (www.cisco.com)
